TECHNICAL FIELD

The present invention relates to physics and engineering, equipment inparticular bladeless fan in the fluid pipe.

BACKGROUND

Nowadays the designation of piping systems and increasing speed andvelocity retention in the various fluid pipe, such as air pipes, oilpipes, rejected pipes, etc, which are designed by using engineeringcalculations to suit the specific work by selecting the pipeline size,pipe installation system, pressure and velocity retention device orpower that enough to push from source to destination. There will be adifference in the work created, which has the weakness point. It issuitable for the specific work, but it is not for general. Theadditional solution is to increase the number of liquid sources atvarious points for reducing the length of the pipe that can control thepressure easily, but this method is more expensive for using inindustrial. Another popular method is to use liquid pressure boostingdevices, but there are disadvantages. The pressure at the source isstrong. But the pressure at the destination drops. The problem is solvedby adding some device inside a pipe such as a turbine fan to speed up ormaintain speed constantly. By using the fan inside the pipe to increasethe movement or increase the speed inside the pipe, the disadvantage isthat uses a lot of devices, more noise and uses more energy.

Patent WO 2010/109169 A2 disclosed the apparatus with a turbine orbladeless fan and power generator. The turbine is located inside achannel that like a pipe to send fluid, such as water, air, etc. Andflow out in a spiral pattern. This is different from the presentinvention. The characteristic of the fluid that flow out in a continuousspiral pattern. And when used in the pipeline, it requires a higherenergy than the fluid flowing straight. Unlike the present inventions,the direction of the fluid will flow forward.

Patent EP 2623328 B1 disclosed the dry blower. It consists of a longtube with an internal fan to speed up and install it throughout theline. The air flow, air passages and internal heating devices. This isdifferent from the present invention. This patent has the internalheating apparatus and the single layer pipe type. The installation ofthe inside fan cannot be used in the pipeline system in the buildingbecause it is difficult to maintenance when one of the fans defect. Thatis difficult to change because the pipe inside the building and the wallclosed.

Patent WO2006/078434 A2 disclosed the fluid motion and water movement incavity. By using the device with fan and motor inside the cavity. Thisis different from the present invention. Because this patent uses moreequipment and uses a fan with propeller that is more energy costs anddifficult to maintenance.

The present invention will be show in the description which need lessenergy and easy to maintenance due to less equipment and fan withbladeless and no sound or light sound. That is suitable for using in theconstruction industry and pipeline system in the buildings or pipelinein the oil and gas industry.

DETAILED DESCRIPTION

According to aspect of the present invention bladeless fan in the fluidpipe comprising,

The two-layer hollow tube is divided into outer and inner layers. Thereis the fluid intake form outer layer (8) and the fluid release to innerlayer (9). To place the hollow tube around the perimeter of the pipe inhorizontal position at least one position. In addition, it is possibleto create a welding pipe at the fluid outlet to the inner layer byspacing it periodically that likes small hollow tube or blocked pipe. Atthis position where the fluid intake point from the outer layer and thefluid release to the inner layer that place the hollow tube around theperimeter of the pipe in horizontal which is called the bladeless fan.

The invention of two-layer hollow tubes can design the fan in the fluidpipe in three forms: 1. As a bladeless fan separate the componentsattached to the pipe. 2. As a bladeless fan attached to the tube. 3. Thetwo hollow tubes melt to the one piece tube.

Form 1: Build the device that like the bladeless fan is attached to thepipe as shown in FIG. 1, and can be placed the fluid sorting devices asshown in FIG. 2, that including of,

From FIG. 3 the bladeless fan attached at the pipe consist of the hollowtube (1), that is characterized by two hollow tubes, the outer layer andthe inner layer attached at the top of bladeless fan (2) with a splitpipe (4), which acts to transfer the fluid along the pipe, that isdepend on each of engineering field. The upper bladeless fan is attachedto the lower bladeless fan (3), which has characteristic design forsplitting and then there is the fluid from the outer layer and releasethe fluid to the inner layer. To place the hollow tube around theperimeter of the pipe in horizontal at least one position.

To consider the attachment of hollow tube (1) and the top of bladelessfan (2) shows in FIG. 4. The upper view of FIG. 4 shows the top viewwhen turn the split pipe (4) to upper and turn the hollow tube (1) tothe left. The top of bladeless fan is in the middle (2) and the lowerbladeless fan (3) is on the right. The cross section on the axis A (6)is (7). The special characteristic is the hollow tube that be protrudeand open end that locate same axis to the split tube (4). Whenconsidering the circle B, it will be seen the details as follows: Theouter layer fluid intake (8) and the inner layer fluid release (9)becomes a bladeless fan that consisting of a part of hollow tube (1) anda part of lower bladeless fan (3) at the area of top bladeless fan (2),that maintain the fluid velocity in the pipe and split pipe (4) atconstant or closely.

To consider the attachment components of the hollow tube (1) and the topbladeless fan (2) as shown in FIG. 5. The top image of FIG. 5 describesthe top view when the turn split pipe (4) to upper and the lowerbladeless fan (3) is on the right hand side. The cross section of axis C(11) is (12) that show the wall of the components. When consider thecircle D, the wall of the lower bladeless fan (3) protrude like a beak.The shape of the curve and the tallest (10) are waiting to be assembledinto a bladeless fan here. It is possible to install a welded pipe atthe fluid release to the inner layer periodically. Its characteristic isboth a small hollow tube or block pipe. The one end is attached to (10).

To consider the lower bladeless fan (3) as shown in FIG. 6, the top leftimage show the lower bladeless fan (3) and the right hand show the topview of the lower bladeless fan (3). When the lower bladeless fan (3)cuts along the symmetry axis E (13), the image is E-E (14) that be theinside view. To consider the circle F by case, there is the endinghollow tube (15) and at the surface of the ending hollow tube (15) caninstall the welded pipe at the fluid release to the inner layerperiodically. Its characteristic is both a small hollow tube or blockpipe. The other side of both a small hollow tube or block pipe isattached to (10) by placing one line. In case placing more than oneline, the condition is periodically location. The appropriate spacing iseach spacing line that has the equally or similar spacing as measuredfrom the perimeter of area (10) and/or (15) one or the other. Theinstallation of a small hollow tube or block pipe can be made byattaching to one inner layer of the top or lower bladeless fan, thenconnect it to the opposite side later, or bring a small hollow tube orblock pipe to attach one or the other.

FIG. 7 shows the fluid sorting apparatus in various views as shown inthe figure and describes the installation of the fluid sorting apparatus(16). The installation of a fluid sorting apparatus (16) suitable forinstalled below the lower bladeless fan (3). Its characteristic is solidattach to the pipe. There is hollow tube inside various sizes tube likehoneycomb (or closely) for flowing the fluid thoroughly. That can bedesigned in any form. The appropriate form depends on the usage thattake into account the length of the fluid sorting apparatus (16) and theinstallation of internal hollow tube. The length of the arrangementapparatus varies with the pressure drop and to increase the frictioninside the pipe. If the design is too short, it will not be possible toarrange the fluid line. It must be relatively calculated to the velocityand pressure inside the flow pipe and the hollow tube size. Theappearance of the arrangement that occur from the inside hollow tube(17), which can be seen in the top view of the bottom image in FIG. 7.The designation must be careful of the design in polygons form, such astriangles and square, etc. Because the polygons cause heat when thefluid move high speed that not suitable as it should be.

When the lower bladeless fan is attached to the fluid sorting apparatusalong the symmetry axis J, it shows the image of the fluid flow throughthe channel as shown in the low left hand. When the top bladeless fan isattached at the symmetry axis G, the image is in the top right hand. Tosee the bladeless fan in the circle H, which enlarges the circle H tothe right image below.

The process of the bladeless fan in the fluid pipe is divided into 2cases, that including of,

Case 1: When hollow tube (1), the top bladeless fan (2) and the lowerblade fan (3) are assembled together, the process will occur. The fluidflows from the hollow tube (1) which has two parts: the outer layer andthe inner layer. The inner fluid is the fluid used in the piping system.The fluid in the outer layer flows into the assembled bladeless fan tomaintain the flow velocity of the fluid constant or closely. When thetwo fluids layer flow from the hollow tube (1) directional to theplacement of top bladeless fan at the area that the top and lowerbladeless fan be assembled to a bladeless fan. The fluid from the outerlayer hollow tube (1) through the outer layer fluid intake (8) then thefluid flow to the inner layer fluid release (9). That cause the fluidmovement directional to the lower bladeless fan. The pressure in thisarea is decreased. As a result, the fluid from the inner layer hollowtube (1) flows instead. That cause the continuous flow in the entirearea. At the upper bladeless fan section has a split pipe (4), the fluidfrom the inner layer hollow tube (1) has two direction that one flow tothe split pipe (4) and the other passes both section bladeless fanthrough the hollow tube that be attached it. That cause the velocity ofthe fluid in the hollow tube (1) constant or closely along the path,even with a split pipe (4).Case 2, when hollow tube (1), the top bladeless fan (2), the lowerbladeless fan (3) and the fluid arrangement device (16) are assembledtogether. The operation is similar to case 1 and when the fluid flowsthrough the lower bladeless fan and flow into the fluid sortingapparatus (16) that installed next to the hollow tube or in the lowerbladeless fan both or one and other one, the fluid is arranged in theshape of the inner hollow tube of the bladeless fan (17). That cause thefluid flow out articulately in line. The installation of the fluidsorting apparatus (16) can be installed in all areas of the hollow tube(1), except the outer layer fluid intake (8) and the inner layer fluidrelease (9). That is, the appropriate location are before or after theinner layer fluid release (9) or both. The most appropriate location isnearby the split pipes (4).

Form 1 can reduce the split pipe (4) at the upper bladeless fan forusing in areas where there are no split pipes in the system. The topbladeless fan (2) and the lower bladeless fan (3) can be divided intotwo or more components and then assembled in the same manner as theassembled top bladeless fan (2) and the lower bladeless fan (3)together.

Form 2 is a bladeless fan that attached or melt to the pipe. As shown inFIG. 9, that is, the implement of a bladeless fan (19) which has thesame characteristics as the bladeless fan from Form 1 assembled already.That can be attached to a hollow tube (1) or for some path to a hollowtube (1) or both with both sides of the bladeless fan as in figure. Thehollow tube (18) has the base or not. Form 2 is suitable forinstallation without split pipe (4). It can maintain the fluid velocityin the pipe to be constant or closely. The more high pressure transmitat the beginning from the fluid source. There will be high pressure inthe beginning and less pressure in the pipe end. It also saves moreenergy.

Form 3 creates a two-layer hollow tube into a single tube. It looks assame as FIG. 9. The difference is the mold implementation of thebladeless fan and hollow tube together. That become a long pipe with thesame process.

In addition to the three form above, they can also be applied to onesingle hollow tube.

Form 4 is the single hollow tube that attach to the bladeless fan withabove process, that is, it has the outer layer fluid intake (8) and theinner layer fluid release (9) wherein the fluid from the inner layerfluid release (9) flow through the single hollow tube instead of theinner layer of two hollow tube. And the outer layer fluid intake (8)will not receive the fluid from the outer layer of the two hollow tubes,but will receive the fluid from the split pipe that is not a singlehollow tube. The fluid from the bladeless fan will flow through thefluid intake and pass to the fluid release point into a single hollowtube. So the fluid inside a single hollow tube moves forward. That causethe pressure at area decrease. When the density is lower, the fluid fromthe high pressure region flow displacement. The fluid dynamics occur atconstant speed or close to the single hollow tube.

FIG. 10 is a schematic block diagram of fluid movement processembodiment that describe the process of the whole system comprising;

The fluid flow from the fluid source (100) through the pipe (101), wherethe line image in the diagram is represented as a whole pipe. When thefluid enters the pipe (101), it will have a constant velocity or closeto the fluid velocity from the fluid source (100). When the fluid passesthrough the bladeless fan installation point (201), the bladeless fanwill work as the fluid density changes. The Fluid passed (201) willtravel along the pipeline to the point where the bladeless faninstallation point (202) and pass to the split pipe that make the fluidmove in two directions: to the bladeless fan installation point (203)and to the end point (304), which causes the area near the bladeless fan(202) change densities. This allows the bladeless fan (202) to releaseadditional fluid to accelerate and make the fluid from block pipe flowfaster to maintain the velocity of the two split pipes to be constant orclosely. Therefore, the pipe that split to the end point (304) has aconstant velocity or close to the fluid velocity from the fluid source(100). The fluid flowing through the pipe to the bladeless faninstallation point (203) will travel further along the pipe (203). Thefluid in the pipe will have a constant or closely velocity and travel tothe bladeless fan installation point (204). The fluid flow through thepipeline to the split pipe 2 ways. There is the end point (301) and aseparate to the bottom of the diagram. The fluid that split to the endpoint (301) will have a constant or closely speed. The bladeless fan(201), (202), (203) and (204) keep the speed constant or closely in thepipeline. The other way fluid flow into the split pipe and travels tothe bladeless fan installation point (205), and when the fluid passes(205) to the split pipe that formed into a two-way junction. There isthe end point (303) and the bladeless fan installation point (206). Thesplit pipe that travels to the end point (303) will have constant speedthroughout the pipeline. Even if the angle of the pipe is split again.Because the bladeless fan installation point (205) will provideadditional fluid and fluid before this point of installation is fasterto distribute the density constant. The split pipe that travels to thebladeless fan installation point (206) will have a constant or closelyspeed. The fluid travel from the bladeless fan installation point (205)and flow to the bladeless fan installation point (206) and when it pass(206) to the end point (302) at constant or closely speed from the fluidsource (100).

In case of form 4, the pipe is a single hollow tube. The case of thefluid source (100), that including of,

Case 1 the pipe (101) is a single hollow tube. The fluid source (100) isdivided into at least two sources so that the fluid flow to the pipe(101) and the fluid separates to the bladeless fan at another fluidsource.Case 2 the pipe (101) is a single hollow tube. The fluid source (100)has a single source with a fluid separator pipe (101) and a fluid pipeto the bladeless fan with fluid from the same fluid source.

Table of appropriateness to choose the work pattern. With bladeless faninstallation in the diagram.

Bladeless fan installation number Appropriate pattern 201 1, 2, 4 202 1,4 203 1, 2, 4 204 1, 4 205 1, 4 206 1, 2, 4 201, 202, 203, 204, 205, 2063

In the last line of the above table is the melting or forming of form 3can be done by melting the whole pipe system or make a partial melting.There are more than one bladeless fan location in the melting process.Then each piece is melted and assembled into the pipe system. Thismethod is not comfortable at the industry level because it need tochange the melting pattern often.

Form 2 has the disadvantage that it only suits for some installationpoints. Because the split pipes should be in the bladeless fan and faraway from the fluid release inside the fan. It is not suitable to use inthe split pipe system. There are always split pipes generally.

Form 4 can be used with all bladeless fan installation numbers. However,it is difficult to make the split pipe for carrying fluid and waste ofresources and not suitable in a limited area system. It is necessary tohave the fluid storage area to be put into the bladeless fan and it isnot suitable.
